Add fixtures for KH100, KE100 and KE110 and simulate TRV states (#1726)

This PR adds fixture files for:

- KH100 (UK), hardware 1.0, firmware 1.7.5
- KE100 (UK), hardware 1.0, firmware 2.15.0
- KE110 (EU), hardware 1.0, firmware 1.4.0

The fixtures were collected from physical devices and anonymized for use
in development and testing.

The KE110 fixture is a new device model and has been added to the
appropriate fixture category.

This also improves test suite by adding TRV state simulation to allow tests pass on fixtures that report a non-heating state.
